摘要
根据基桩低应变反射波法的基本原理,选取几种实际工程中常见的典型缺陷桩的反射波曲线进行分析研究,通过研究这些典型缺陷桩的反射波实测曲线,得出常见的典型缺陷桩的反射波曲线特征及其与桩身完整性间关系的几点结论,为提高低应变法判别桩身完整性的准确度和可靠性提供参考经验。
According to the basic theory of low strain reflection wave method of foundation piles detection,we select severa lreflected wave curves of typical defect piles that are commonin practical engineering to analyze.Based on the study of these wave curves,we can conclude characteristics of the frequent wave curve of typical defect piles and the relationship between these curves and the integrity of the pile,providing some reference experience to improve the accuracy and reliability of the pile integrity by using low strain method.
